Miniature rose plant named &#39;Meijelior&#39;

ABSTRACT

A new and distinct variety of rose plant of the dwarf Miniature Class is provided which abundantly forms attractive double blossoms that are a blend of pale orange suffused with light pink in coloration. The growth habit is bushy, low and compact. Very dense medium green semi-glossy foliage is formed that contrasts nicely with the blossom coloration. The new variety is well suited for pot forcing under greenhouse growing conditions to form a distinctive gift plant. There is no particular sensitivity to diseases.

SUMMARY OF THE INVENTION

[0001] The new variety of Rosa hybrida Miniature rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the ‘Meifruije’ variety (U.S. Plant Pat. No. 9,033). The male parent (i.e., the pollen parent) was the product of the cross of the ‘Meineyta’ variety (non-patented in the United States) and the ‘Meisancho’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

‘Meifruije’×(‘Meineyta’×‘Meisancho’).

[0002] The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

[0003] It was found that the new variety of Miniature rose plant of the present invention possesses the following combination of characteristics:

[0004] (a) exhibits a bushy, low and compact growth habit,

[0005] (b) forms in abundance attractive very double blossoms that are a blend of pale orange suffused with light pink in coloration,

[0006] (c) forms very dense medium green semi-glossy foliage, and

[0007] (d) is well suited for pot forcing under greenhouse growing conditions.

[0008] The new variety well meets the needs of the horticultural industry. It is particularly well suited for pot forcing under greenhouse growing conditions to form a distinctive gift plant.

[0009] The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned methods as performed in the South of France has shown that the characteristics of the new variety are strictly transmissible from one generation to another.

[0010] The new variety has been named the ‘Meijelior’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

[0011] The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were one year of age and were observed during May while growing on their own roots in greenhouses at LeCannet des Maures, Var, France. Dimensions in centimeters are shown at the bottom of the photograph.

DETAILED DESCRIPTION

[0028] The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of six month-old specimens of the new variety which were observed during November while growing on their own roots in greenhouses at LeCannet des Maures, Var, France.
